Active Ingredients

The development of cosmeceuticals capable of mimicking the biologicalproperties of the extracellular matrix (ECM) present in the skin tissueis a strategic objective to counteract aging and stress effects byrestoring the optimal functionality of the resident cell populations.

Cytomimetic technology, in the formulations disclosed herein, mimicshealthy, vital parts of the skin tissue environment where skin cellsthrive. Using this mimicry it effectively infuses the skin tissue (ECM)with special, luxurious ingredients to balance, tone and beautify. Thisproprietary technology enhances biological activity by mimicking partsof the macromolecular universe that exist in our skin.

Cytomimetic formulations, that employ the actives of fermented truffleextracts, HA of different Mw, olive leaf extract in thermal water,Falernum fermented grapes, have surprisingly be shown by the inventorsto possess a strong synergism amongst themselves. The effectiveness ofthese naturally-based active ingredients are enhanced when usedtogether, by mimicking the complex actions of bio-stimulation,signaling, repair and protection of their own fully functional ECM.Below, the basis of each individual actives component is discussed.

Truffle Fermented Extract—

Truffles have a number of biological activities, such as antioxidant,antiviral, anti-microbial, hepatoprotective, anti-mutagenic,anti-inflammatory, anti-carcinogenic, and are anti-tuberculoid. (N.Beara et al./Food Chemistry 165 (2014) 460-466). One of the mostpromising truffles, from a biochemical point of view, is Tuber magnatumpreciosa. It is native to Italy, namely the Piedmont, Tuscany and EmiliaRomagna regions. The effects of truffle oil aroma are confirmed by theability of some scent molecules to interact with receptors and triggersome significant signals in human cells. The challenge has been tryingachieve the relevant effects on the skin for cosmetic purposes. Resultsherein demonstrate that fermented truffle extracts contain one or moresubstances, that with a synergistic action, induce the heat shockresponse, eliciting quantifiable beneficial effects on cells.

Surprisingly the inventors have found that by subjecting it to abiotransformation/fermentation process, truffle homogenate showsimproved biological properties, as empirically demonstrated by in vitrokeratinocytes and fibroblasts scratch assay with time lapse microscopy(TLVM) (see Table 1) and by the appearance of new activities that arenot present in the simple aqueous extract, such as the property ofstimulating a response to shock in the cell culture.

The basis of the preservation of the chemical architecture and of thefunctional properties of a cell organism under stressful conditions iscalled homeostasis. A feature of homeostasis is the rapid reaction tostressful conditions by expressing genes, whose products and heat shockproteins are specifically dedicated to function against the stress,while also protecting the cellular components (Lindquist S., 1986, AnnRev Biochem, 55, 1151-1191; Morimoto, R. I. 1993, Science, 259:1409-1410; Morimoto, R I., et al., 1990, In Stress proteins in biologyand medicine pp. 1-36. Cold Spring Harbor Laboratory Press, Cold SpringHarbor, N.Y.).

The response to shocks and, in particular, the heat shock response(HSR), is an ancient and highly conserved cytoprotective mechanism andthe heat shock proteins (HSPs) are among the most abundant proteins inthe biosphere. The fact that they show such remarkable evolutionaryconservation, suggests they are essential for basic cellular function.

A number of studies have shown that the expression of these proteins hasa close relationship with life history, exerting influence on biologicalphenomena such as stress resistance (Morimoto, R. I. and Santoro M. G.,1998, Nature Biotech, 16:833-838.), aging and longevity (Tao D, Lu J, etal. 2004, Acta Biochim Biophys Sin (Shanghai), 36:618-22; Calderwood SK, et al., 2009, Gerontology; 55:550-558).

The heat shock response mechanism for cell protection against stressresults in the down-regulation of many genes and the activation ofothers, whose main function is to help the cell survive. The productionof heat shock proteins, including protein chaperones, is essential forthe folding, repair and recovery of damaged proteins, since it promotescellular viability under conditions that would otherwise induce cellsdeath (apoptosis).

During the aging process the cell reduces its capacity to synthesize theproper amounts of heat shock proteins under stressful conditions. It isthis impairment that may be one of the main factors that contributes toa reduced capacity to maintain homeostasis, and is thus a culprit ofdamage to the cells.

Among the heat shock proteins, chaperonins are one of the most importantclasses, since they prevent the incorrect association within and betweenpolypeptide chains during the folding of newly synthesized proteins,while also protecting the pre-existing proteins under cellular stresses.Chaperonins also function in the absence of stress, namely under normalphysiological conditions, helping cellular proteins to fold correctlyduring synthesis on the ribosome. HSP 70 is one of the most studiedchaperonins.

It is this mechanism that allows the cell to react to external stress.There is strong consideration that the cell membrane bilayer hasfluidity properties that permit sensing of changes in temperature, pH,osmotic and atmospheric pressure, etc. In this respect the cellularmembrane may be considered the key sensor of the cell in regards toexternal stress factors. In fact, following a temperature change, cellscompensate for stress induced disturbances, through physiological andbiochemical mechanisms of homeoviscous adaptation (Vigh, L., et al.,1998, TIBS 40323: 369-374).

In addition, there is evidence that membrane lipids may participate asmolecular chaperones in the folding and possibly in the unfolding ofintegral membrane proteins. Furthermore, the modification of membrane'sphysical state influences the expression of heat-shock genes, simulatinga heat shock condition. Such an outcome can be caused by somepathological conditions or by the interaction of the membrane withseveral molecules.

With particular regard to the skin cells (Maytin, E V., 1995, J. Invest.Dermatol 104:448-455; Edwards M J, et al., 1991, J Invest Dermatol96:392-6; Trautinger F, et al., 1995, Br J Dermatol, 133:194-202; Roh BH, 2008, Ann Dermatol 20:184-9) both dermis and epidermis, expression ofHSPs confers resistance to damage caused by stressors, for instance,sunlight exposure. Maytin (Maytin, E V., 1995, J. Invest. Dermatol,104:448-455) has reported that heat shock proteins play a general rolein the protection of the skin from environmental stressors, but alsoparticipate in the prevention and repair of the damages caused byexposure to light, heat, chemical injuries, and other traumas.

An important feature of heat shock proteins is their role in thecytoprotection and repair of cells and tissues against the deleteriouseffects of stress and trauma. Overexpression of one or more heat shockprotein genes is sufficient to protect against otherwise lethalexposures to heat, cytotoxic drugs, toxins, and tumor necrosis factor-α(Parsell, D. A. and Lindquist, S., 1994, in The biology of heat shockproteins and molecular chaperones. Cold Spring Harbor Laboratory Press,Cold Spring Harbor, N.Y.).

Yeast cells, engineered to overexpress HSP 70 or HSP 104 cross-protectagainst lethal heat shock, H₂O₂ heavy metals, arsenite, anoxia, andethanol toxicity. In vertebrates, modulation of the heat shock responseor the expression of specific heat shock proteins can either limit orprevent the pathology associated with certain chronic diseases.

It is desirable, from a practical point of view, to obtain naturallyderived compounds able to induce the stress response in the cells in theabsence of stress. These compounds could create a preventive/defensivestrategy in the cells, by mimicking the effects of stress, in turnhelping the cells throughout the aging process.

In embodiments, an objective of the present invention is to develop newclasses of molecules able to mimic or activate some fundamental processof life. Attention has been spent on repair mechanisms, which make itpossible for the cells to survive, since these biological strategieshave represented the optimal results of the evolution process forbillions of years. There are many compounds capable of increasing theexpression of HSPs but the majority of these inducers exhibitsignificant cytotoxicity.

To cope with increased demand of multifunctional cosmetic products, theinduction of HSPs by natural, not toxic compounds, come with excellentprospects.

Herein, the inventors have identified as most representative species ofHSP, the 90 and 70, representing the most ubiquitously expressed heatshock proteins, have been taken into consideration. These proteinsrepresent 1-2% of the proteins present in the eukaryotic cells, and arecapable of reaching concentrations of 4-6% in the presence of stress.

The studies conducted by inventors on the effects of truffle fermentedextracts concentration on cell culture (see Table 2) show a progressiveincrease of HSP 70 and HSP 90 level of expression with no toxicity. Thissuggests that truffle fermented extracts contain one or more substances,that with a synergic action, induce the heat shock response, elicitingall the above described beneficial effects on cells.

The discovery of new molecules that are able to activate the stressresponse, by mimicking the effect of stressors, either in the completeabsence of stress or at a lower threshold of stressful conditions, as isthe case of fermented truffle extract, represents an important target inthis innovative approach, since the knowledge accumulated on thismechanism makes for the possibility of developing innovative strategiesfor its use to solve cosmetic problems in regards to skin aging (Cf.Jindal S, 1996, Trends Bioch. Sci 14:17-20; Magalhaes W V et al. 2012,Eur J Dermat, 22(1) 8-13).

An in vitro test was specifically used by the inventors to assess theantioxidant activity on fermented and non-fermented truffle extract(Table 3). Human keratinocytes and fibroblasts treated with H₂O₂ orexposed to UV-A radiation show an increased lipid peroxidation that wassignificantly reduced either by treating the cells with fermentedtruffle extract after the stress or before it.

Hyaluronic Acid—

In the development of innovative cosmeceutics for skin biorevitalizationthere is growing interest in the use of mixtures of HAs with differentMw, with optimized rheological and biological properties. Results hereinshow the efficacy of different sized HA to stimulate the migration ofkeratinocytes and fibroblasts. In particular, the data showed that HA1800 KDa, its intermediate fragments (800 and 200 KDa) and theirmixtures increased the repair/remodeling process and fastened the cellmigration, confirming in particular the efficacy of HA mixtures inbiorevitalizing effect.

Hyaluronic acid, also generically indicated together with its salts ashyaluronans (HA), is a polysaccharide with a linear chain, negativelycharged, composed by the repetition of n disaccharide units(-4GlcUAβ1-3GlcNAcβ1-), wherein the D-glucuronic acid (GlcUA) andN-acetyl-D-glucosamine (GlcNAc), are linked by alternating β-1,3 andβ-1,4 glycosidic bonds. HA is a polysaccharide highly soluble in waterand solutions of HA show a visco-elastic behavior of non-newtonian type.These properties are function of: Mw, (and being HA a linear polymer,the chain length), concentration and external environmental conditions,such as pH and ionic strength. HA has a number of unique properties,shown below, making it one of the most versatile and interestingbiomaterials:

-   -   a) Hydrophilicity and rheological properties of HA: In aqueous        solution the molecules of HA entrap large quantities of water        (about 1000 times the weight of the HA) taking the form of        extended spirals, stabilized by hydrogen bonding between the        hydroxyl groups along the chain. These chains will envelop        between them, even at very low concentrations, for this, even        very dilute, HA solutions have high viscosity, but depend on        sliding speed.    -   b) Lubricating properties of HA: Extraordinary rheological        properties of HA solutions make this compound an ideal candidate        as a lubricant in the biological field. This is, in fact, one of        the actions to which the HA performs in organisms. The joints of        our body are an example of this type of behavior.

More than 50% of HA is present in the skin tissue (Laurent T C andFraser J R., 1992, Faseb J; Oh E J, et al., 2010, J Control Release141:2; Juhlin L. 1997, J Intern Med, 242:61). Despite the high molecularweight and hydrophilicity of HA, it is known to be delivered through theskin tissue in both mouse and human (Brown T J, et al., 1999 J InvestDermatol, 113:740; Brown M B and Jones S A. 2005 J Eur Acad DermatolVenerol, 19:308). The mechanism for transdermal transport of HA has notbeen clearly verified yet, but there are some possible reasons for thepositive effect of HA on transdermal delivery. First, HA is veryhygroscopic and can hydrate the stratum corneum enhancing thepermeability of the skin. Second, the hydrophobic patch domain in HAchain can enhance the permeability of HA across the stratum corneum.Third, HA receptors distributed in the skin tissue may facilitate thelocalization of HA in the skin tissue (Brown M B and Jones S A, 2005, JEur Acad Dermatol Venerol; 19:308; Wang C, et al., 1992 Histochemistry,98:105; Tammi R et al., 1991, J Invest Dermatol 1991; 97:126). Moreover,it is reported that HA can induce the proliferation, migration,adhesion, and differentiation of keratinocyte (Lokeshwar V B et al.,1996, J Biol Chem, 271:23853; Masellis-Smith A et al., 1996 Blood,87:1891). HA can also enhance the proliferation of fibroblast throughCD44 receptors on the cell membrane (Yoneda M et al., 2004, J Cell Sci,90:265). For all these reasons HA, despite its size, when applied to theskin, is absorbed and operates as a carrier of other molecules (U.S.Pat. No. 9,220,784 B2, hereby incorporated by reference).

HA is widely distributed in nature. It has been identified in varioussoft tissues (synovial fluid, skin, umbilical cord, cockscomb, vitreoushumor of the eye) and in some prokaryotic cells, in which it creates amucoid capsule surrounding the cell. In vertebrates the HA has a widevariety of functions: in the skin it ensures tissue hydration; in thecartilage it binds to proteoglycans to adjust the content of water andions, to stabilize tissue physical properties and cell-substrateinteractions. The average molecular weight of the HA of synovial fluidand the umbilical cord is 3,000-4,000 KDa.

The biological responses elicited by the HA depend strongly on its Mw,in particular the accumulation of low Mw HA is an early signal ofalteration of the ECM, which activates the shelter responses at tissuelevel, while a preponderance of high Mw HA signifies a situation of goodhomeostasis. As a result of its properties and biological functions, HAhas a high added value (its market value far exceeds that of othernatural polysaccharides), with applications ranging from the medicalsector to the cosmetics sector.

In many HA applications, the performance depends on its Mw. For this,the mean molecular weight of the HA and a polydispersion index Mw/Mn(measuring the breadth of the molecular weight distribution curve, whereMn is the number average Mw, defined as the total weight of all thepolymer molecules of a sample divided by the total number of molecules,and Mw is the weight average molecular weight, which takes account ofthe different mass of these molecules) needs to be the gold standardconsidered during the development and production processes (Camenisch TD et al., 2000, American J. Respiratory Cell and Molecular Biology 23,431-433, hereby incorporated by reference).

In recent years, scientists have been studying the correlation betweenHA Mw and physiological functions (Raoudi D. et al., 2008, Wound Repairand Regen, 16(2 Suppl), 274-87; Ke, Sun Qiao, et al., 2011, Food ChemToxicol., 49(10), 2670-5; Cowman, L et al., 2015 Frontiers inImmunology, 6, 261; Ferguson, R. et al., 2011, Int J Pharm, 420 (1Suppl), 84-92). Generally, native HAs (Mw ranging from 2000 to 800 KDa)are space-filling molecules with anti-inflammatory and anti-angiogeniceffects, while lower Mw HA (Mw<50 KDa) may be involved in aproinflammatory process (Frenkel J. S., 2014, Int Wound J, 11, 159-163).In particular, there has been an increasing effort to clarify the roleof HAs in the interaction with the epidermis/dermis tissues (Ghosh, P.,& Guidolin, D., 2002, Current Abstracts Seminars in Arthritis andRheumatism, 32(1), A2-A4). HA has also been reported to be a freeradical scavenger, presenting an antioxidant function. It enhances thewound healing process and presents both angiogenic (Gao F. et al., 2010,Matrix Biol., 29(2), 107-16) and immunostimulatory activity (Ke et al.,2011 Food Chem Toxicol., 58, 401-7).

Nevertheless, given HA turnover, all HA fragments have a physiologicalfunction, as could be expected, that is often very important in thehealing processes, biological tissue homeostasis and biosynthesis ofECM. Native HA is reported to be fragmented in smaller molecules duringECM degradation after acute tissue injury, in order to activate the hostinnate immune response by recruiting macrophages and other specificcells, to produce chemokines required to begin repair/restoration oftissue integrity.

Due to water-attracting characteristics in tissue repair, for example,long chain HA has cushioning and visco-elastic properties, that create aporous scaffold onto which the cell might migrate; on the contrary,medium-size HA fragments (100-250 kDa) have been found to promote cellmigration and contemporarily to stimulate and modulate pro-inflammatorycytokines production; finally very small fragments (4 saccharides) havebeen found to induce chemotaxis (Frenkel, J. S., 2014, Int Wound J, 11,159-163.).

Vigetti and collaborators have reported that small HA fragments, rangingfrom 3 to 25 disaccharides (1.2-10 kDa), have inflammatory effects andshow pro-angiogenic activity in human cell models (Vigetti, D., et al.,2014, Biochim Biophys Acta., 1840(8), 2452-9). Relative to this, arecent report has shown that HA fragments stimulate chemokine andcytokine gene expression interacting with TLR-4 (Jiang D et al.,Physiological Reviews, Vol. 91 no. 1, 221-264). RHAMM receptor wasmainly involved in the cell migration. As a matter of fact, RHAMM-HAinteraction does play an important function in tissue injury and repair(Viola et al., 2015, Glycoconj J., 32(3-4), 93-103).

Although sometimes contradictory, the set of knowledge on thedifferentiated effects of HA as a function of its Mw, is an importantpremise for the construction of innovative cosmeceuticals, in which theoptimization of mixtures of HAs with different Mw allows for theobtainment of effective biological responses in biostimulationprocesses, to contrast skin aging. In addition, although many reportshave confirmed the differences relating to HA Mw, there have been noexperimental highlights at the biological level of these differentcompounds.

Prompted by this knowledge and shared experience of diffused confusionin assessment and in the relationship between HA size and function, theinventors addressed the question through rigorous methods. Byidentifying an optimal range of HA fragments and their biochemicalactivities, and by using in vitro models and specific biochemical test,the inventors have elucidated the effect of specific HA fragments andtheir mixture when they interact with membrane receptors, in modulatingcellular biostimulation, wound repair, cell migration, and cytokineexpression. Results herein show the efficacy of different sized HA tostimulate the migration of keratinocytes and fibroblasts. In particular,the data showed that HA 1800 KDa, its intermediate fragments (800 and200 KDa) and their mixtures increased the repair/remodeling process andfastened the cell migration, confirming in particular the efficacy of HAmixtures in biorevitalizing effect.

With acidic hydrolysis in a heterogeneous phase (Melander C. andTommeraas K., 2010, Carbohydrate Polymers 82, 874-879; herebyincorporated by reference), a full array of HA fragments of differentsize (Table 4) was obtained, with identical structural disaccharidesunits, thus ensuring that biochemical and biological outcomes are notascribed to a HA modified chemical structure. ¹H-NMR analysis confirmedthese results. The structural and rheological data (Viscotek analysis)confirmed that products are similar to the ones obtained byhyaluronidase in vivo and, for this purpose, suitable to be tested forin vitro biological response.

To elucidate the biological roles of HA fragments by studying specificbiomarkers from the preliminary phases of wound healing process, an invitro scratch test has been used with TLVM (D'Agostino et al., 2015, BMCcell biology, 16:19, hereby incorporated by reference) on humankeratinocytes and fibroblasts. The highest Mw HA samples led to completerepair in a shorter time; however, all the HA fragments tested enhancedthe scratch repair rate compared to the control (Table 5).

Interaction between different sized HA and relative specific receptorswas investigated to improve knowledge of the biochemical basis in theactivation/silencing of pathways relative to HA and its degradedproducts in vivo. Results have shown the efficacy of different sized HAto stimulate the migration of keratinocytes and fibroblasts. Inparticular, the data showed that HA 1800 KDa, its intermediate fragments(800 and 200 KDa) and their mixtures increased the repair/remodelingprocess and fastened the cell migration, confirming in particular theefficacy of HA mixtures in biorevitalizing effect.

Molecular analysis at gene and protein level corroborated the dataderived from time-lapse experiments. HA exerts biological activitythought interaction with its receptors on cell surface; in particularCD44, the main HA receptor, interacting with HA, triggers differentbiological responses, ranging from cell proliferation and ECMdegradation to angiogenesis and inflammation.

All HA analyzed herein activated CD44, but the major responses werefound in presence of HA 1800-800 KDa (Table 7). All HA samples increasedRHAMM expression, however results were significantly higher for 200 KDa(Table 7).

TLRs are receptors of innate immunity and TLR-2 and TLR-4 may bind HAfragments, inducing signaling. Differently from CD44 response, TLR-4activity, correlated to inflammatory process, is significantlydown-regulated in all HA tested (Table 7). Gene expression data of HAreceptors were confirmed by immunostaining.

In order to follow-up the biochemical cascade turned on by HA-receptorinteraction, the expression profile of key cytokines possibly involvedhave been evaluated. The results herein show an up-regulation of TGF β-1and TNF-α in presence of all HA treatments (Table 7). Therefore, allhyaluronan fragments tested were both safe and biologically active.Furthermore they may support cell activation, therefore helping in skinrepairer procedures and biological remodeling.

In consideration of the differentiated biological effects thatcharacterize the HA as a function of its Mw, and of the heterogeneity ofthe HA molecular population naturally present in the ECM, a cytomimeticformulation was synthesized by mixing HA of different Mw.

The experimental data (Table 5), using the test model of wound healingtime lapse microscopy of human chondrocytes and fibroblasts, showed thatthe best results were obtained using mixtures formed by comparableamounts of HA 1800, 800 and 200 KDa. In fact, the synergism between thebiological properties of these different HAs reduced the healing time by50-70% in both experimental models. An in vitro test was specificallydeveloped to assess the antioxidant activity of the mixture of HAs1800+800+200 KDa (Table 8). Human keratinocytes and fibroblasts treatedwith H₂O₂ or exposed to UV-A radiation show an increased lipidperoxidation, that was reduced either by treating the cells with HAs1800+800+200 KDa after the stress or before it.

Olive Leaf Extract in Thermal Water—

Among the active ingredients that have a strategic role to drawcosmeceuticals effective in protecting the skin and preventing skinaging, compounds with antioxidant activity are considered elective. Ofparticular interest are the natural antioxidants obtained generally byextraction from plant sources. In order to help achieve optimalprotective effects as a radical scavenger, it is preferable that therebe a mixture of compounds with different spectrums of antioxidantactivity. A particularly interesting source of active ingredients withantioxidant activity are Olive leaves (Olea europaea). Only fresh leaveswere used in the extracts, instead of dried leaves or reconstitutedpowders. Experimental data herein shows that liquid Olive leaf extractmade directly from fresh leaves has a broader spectrum potency than haspreviously been the case, including a synergistic action with thermalmineral water on wound closure time.

The extract of olive leaves is characterized by the presence of asignificant quantity of oleoeuropein (IUPAC name4S,5E,6S)-4-[2-[2-(3,4-dihydroxyphenyl)ethoxy]-2-oxoethyl]-5-ethylidene-6-[[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)-2-tetrahydropyranyl]oxy]-4H-pyran-3-carboxylicacid, methyl ester). This composition is accompanied by minor amounts ofstructurally related polyphenols with antioxidant activity as10-hydroxyoleuropein, ligstroside, and 10-hydroxyligstroside. Oleuropeinhad activity as an agonist of the G-protein estrogen receptor (Eric R.et al., 2014, Molecular and Cellular Endocrinology 389 (1-2): 71-83).

The ‘natural balance’ of antioxidant actives in a fresh Olive leafextract provides a more powerful free radical scavenging capacity asopposed to when the individual components are isolated. This involves asynergistic action between flavonoids, oleuropeosides and phenols.

Aqueous systems are used when preparing the extract of Olive leaf,leaving the homogenized leaf to extract for 24-48 hours.

A strong innovation in the field of phytoextracts has been the use ofthermal water with this special composition and these therapeuticproperties as an extraction system. This helps create importantsynergies between the biological effects of active extracts and those ofthe extracting system. In this respect, the thermal spring water is ofparticular interest, including that obtained from the Thurio spring atthe Spezzano Thermal Baths in Italy. Thanks to the abundance of peculiarmicroelements, it is an active principle of choice. These microelementsprovide outstanding soothing properties. As reported in Table 9, usingthe in vitro keratinocytes and fibroblasts scratch assay with TLVM, asignificant synergism of action between the thermal water and the activepresent in the olive leaves extract. Its almost half the time of theclosure wound.

In vitro testing was used by the inventors to assess the antioxidantactivity accomplished from the Olive leaf extract in thermal water(Table 10). Human keratinocytes and fibroblasts treated with H₂O₂, orexposed to UV-A radiation, have shown an increased lipid peroxidation.This was reduced by either treating the cells before or after thestress, using Olive leaf extract in thermal water.

Fermented Falernum Grapes—

Falernian wine (Latin Falernum) was historically produced from Aglianicograpes on the slopes of the Falernus mountains, near the border ofLatium and Campania region of Italy. Falernian fermented grapes areparticularly rich in polyphenols and anthocyanins and provide stronggeneral antioxidant and free radical scavenger activity. However, itsantioxidant effects directly on skin cells are not determined. Herein itis shown that Falernian fermented grape must has an importantbiorevitalizing action (Table 11) and significant antioxidant activityin human skin cells as tested, namely, human keratinocytes andfibroblasts.

The Falernus mountains area is now occupied by the modern day vineyardsof Rocca di Mondragone and Mount Massico. Grapes of Falciano del Massicowere collected in late August, when they are not yet fully mature. Thegrapes, after baling and homogenisation, are left to ferment for 48hours at 10° C., clarified by filtration under pressure and thenpasteurized. The ruby liquor that is obtained can be defined asfermented grapes of Falernum. The inventors have determined that thisliquor has an important biorevitalizing action (Table 11) andsignificant antioxidant activity in human skin cells as tested, namely,human keratinocytes and fibroblasts (Table 12). In fact, humankeratinocytes and fibroblasts treated with H₂O₂, or exposed to UV-Aradiation have shown an increased lipid peroxidation that was reduced byeither treating the cells before or after the stress with fermentedFalernum grape must.

Cytomimetic Formulas and Synergism of their Actives—

The skin extracellular matrix (ECM) develops at the tissue level aseries of complex functions indispensable for the correct functionalityof the cell population. The realization of a cytomimetic formula for theskin tissue, able to mimic the ECM complex functions, must ensure thetissue biorevitalization, an effective anti-inflammatory/radicalscavenger activity and the activation of repair molecular mechanisms.

The inventors have found that by using the natural actives together, acytomimetic formula was obtained capable of developing theabove-described complex functions. The strong synergistic effect betweenthe active employed is absolutely unpredictable. (Fermented truffleextract, mix of HA 1800, 800 and 200 KDa, extract of olive lives inthermal water and fermented Falernum grape must). These are moreeffective even at extremely low concentrations, rather than employingthe various actives individually.

In vitro wound healing experiments (Table 13) have shown thatcytomimetic formulas were superior in prompting wound closure. Thepotent synergism between actives of cytomimetic formula is evident whencomparing Examples 1, 5, 9 and 11, with Example 13 in which the activesare present up to three orders of magnitude or less.

In vitro testing was specifically developed to assess the antioxidantactivity accomplished by the cytomimetic formulas (Table 14). Humankeratinocytes and fibroblasts treated with H₂O₂ or exposed to UV-Aradiation have shown an increased lipid peroxidation. This wassignificantly reduced either by treating the cells before or after thestress with cytomimetic formulas.

The potent synergism between actives in the cytomimetic formula is alsoevident in the production of heath shock proteins, in particular HSP 70and HSP 90, which gradually increase their expression when the cells aretreated with increasing amounts of cytomimetic formula. Table 15, infact, demonstrates the potent synergistic effect of actives present inthe cytomimetic formulate that, as reported in the Example 15 arepresent up to three orders of magnitude in less respect to that reportedin Example 3 for the fermented truffle extract alone.

Also analysis of gene expression elicited by Cytomimetic formula instressful conditions, performed at 0.1 and 0.5%, (Table 16) demonstratedthe potent synergistic effect of actives present in this formulae. CD44,RHAMM, TGFβ-1, TNF-α and IL-6 were all up-regulated increasing withcytomimetic formulae concentration, and only TLR-4 activity, correlatedto inflammatory process, was significantly down-regulated.

In embodiments of the cosmeceutic products, cytomimeticformulas/formulations can be used at concentrations ranging from 0.1 to50% w/w.

To assess the efficacy of a cosmetic composition using cytomimeticformulations, a clinical study was performed on 10 subjects (women),aged between 30 and 54 years, for 28 days. The ingredients of the basecomposition, and the base composition with a cytomimetic formula aredescribed in Examples 20 and 21.

The efficacy has been proved using instrumental, non-invasive methods:moisture of comeum layer (Corneometry), sebumetry, elasticity andfirmness, SELS (Surface Evaluation of Living Skin) parameters:roughness, smoothness, the scaliness degree, wrinkles.

Determination of profilometry (micro-relief). Profilometry wasdetermined instrumentally, by Visioscan VC 98 (Courage+Khazakaelectronic GmbH). This testing method is called SELS (Surface Evaluationof the Living Skin) which is based on the graphical illustration of theskin surface under conditions of special illumination and electronicprocessing of the image, quantified in pixels. “Skin smoothness” (SEsm),can be quantified by finding the average between the depth and width ofthe skin wrinkles. The smooth skin has a low variation of grey, makingthe histogram of the level of grey distribution narrow, resulting in avery small SEsm value. “Skin roughness” (SEr), can be demonstrated byusing the levels of grey in comparison with the roughness of the entireimage. An increased value of this parameter expresses a reduction of theroughness of the analyzed area. “Scaliness” (SEsc) is expressed as thenumber of pixels whose level of grey is over the threshold limit; thereduction of this parameter is correlated with a low exfoliation of theskin. “Wrinkles” (SEw)-skin wrinkles are calculated from the proportionof horizontal to vertical wrinkles. The value of SEw is higher the morevisible the wrinkles are from the point of view of the width and thedepth.

Skin elasticity was determined instrumentally (Cutometer MPA580—Courage+Khazaka electronic GmbH). The elasticity curve obtained by asuction/elongation cycle of the Cutometer, respectively 10 repetitivecycles for the assessment of the area parameter: Among these parameters,in this study the relevant and correlative ones for elasticity andfirmness were selected: R2 (Ualufl—gross elasticity, represented by theratio between the ability of redeformation and final distension, thecloser this value is to 1, the more elastic the skin becomes. R5(Ur/Ue)—net elasticity, the ratio between the immediate retraction andthe immediate distension, expresses the ability of the skin recoveryafter the deformation.

Skin hydration was performed instrumentally, through corneometry,measuring the capacitance. The variations in the dielectric constant ismeasured by using the water content in the epidermal superficial layerand the level of hydration.

Skin lipid levels in the skin have been quantified using a sebumeter, bymeasuring the absorbance of a plastic film impregnated with sebum. Thefilm becomes more transparent in the presence of the lipids. The sebumvalues can be measured between 50-300 μg/cm³.

The clinical results obtained as described in Example 22, showsignificant improvement of skin physiological parameters after usingbasic composition with cytomimetic formulate as compared with the basecompositions demonstrated in vivo biological effect found in vitro. Theresults show improvement in all profilometric parameters: reducedscaliness with 116%, improved roughness and smoothness, with 76.6% and,accordingly 47.5% and wrinkle reduction (73.9%). What is veryinteresting is the balancing effect on lipid content in the stratumcorneum. This can be explained by the restoring effect at intercellularlevel. In the oily skin, the sebum level decreased with 35.67%. The dryskin level increased by 74.30%. In the same time, the base formula usingcytomimetic formulate performed a better moisturization (33.33% higher)and an improvement of skin elasticity (R2 40%, R5 50). The comparativeperformance in vivo (clinical results) of base cream and base creamusing cytomimetic formulate are presented in Table 19.

The body of results obtained, as shown through in vitro and in vivoexperiments, demonstrate the superiority of the aesthetic treatmentsthrough the cytomimetic formulas of the invention. Non-limiting examplesare given below, describing the production, characteristics and use ofthe formulate of the invention.

Example 1 Preparation of Fermented Truffle Extract

1 Kg of Tuber magnatum preciosa, a white truffle collected from Alba,Italy, were washed first with water many times, then three times with0.1 M sodium phosphate buffer at pH 6 and minced into small pieces. Thetruffle pieces were suspended with 0.1 M sodium phosphate buffer at pH 6in the ratio 1/10 w/v and homogenized for 1 hour with an ultra Turraxblender.

The slurry was transferred into a 20 L fermenter and, after addition of10 g of lyophilized Saccharomyces cerevisiae inoculum, was fermented for24 h at 30° C. with a flux of sterile air of 2 L/min, whichautomatically controlled the pH at 6. During fermentation its evidentthe partial clarification of the slurry. At the end of fermentationprocess the slurry was clarified by continuous centrifugation on alfaLavall centrifuge and the clear supernatant was lyophilised, obtaining110 g of a pale yellow fine powder of fermented truffle extract.

Simple truffle extract was obtained by homogenizing washed truffle andmaintaining under agitation of the slurry at 4° C. for 24 h, beforeclarification and lyophilization.

Fermented yeast extract was obtained by suspending 10 g of lyophilizedSaccharomyces cerevisiae in 10 L of 0.1 M sodium phosphate buffer at pH6. The suspension was transferred in a 20 L fermenter, and fermented for24 h at 30° C. with a flux of sterile air of 2 L/min, automaticallycontrolling the pH at 6. At the end of fermentation process thesuspension was clarified by continuous centrifugation on Alfa Lavallcentrifuge and the clear supernatant was lyophilised.

Example 2 Fermented Truffle Extract: In Vitro Keratinocytes andFibroblast Scratch Assay, Using TLVM

HaCaT, a spontaneously transformed non-tumorigenic human keratinocytescell line was provided by Istituto Zooprofilattico, Brescia, Italy andthe cells were cultured in Dulbecco's Modified Eagle Medium (DMEM),supplemented with 10% (v/v) heat inactivated Fetal Bovine Serum (FBS),penicillin 100 U/ml and streptomycin 100 μg/ml. DMEM, FBS, Pen-Strep PBSand Trypsin were provided by Gibco Invitrogen (Milan, Italy).

A human dermal fibroblasts cell line immortalized with hTERT (HDF cells,BJ-5ta, ATCC CRL-4001), was cultured in a 4:1 mixture of DMEM and Medium199 supplemented with 0.01 mg/ml hygromycin B and 10% (v/v) FBS. Allmaterials for HDF culture were purchased from ATCC (USA). The cells weregrown on tissue culture plates (BD Falcon, Italy), using an incubatorwith a humidified atmosphere (95% air/5% CO₂ v/v) at 37° C.

Briefly 12-wells (pre-coated with collagen) were seeded with HaCat orHDF cells until complete confluence was reached. Scratch wounds werecreated mechanically with a sterile pipette tip (Ø=0.1 mm). Uniformlysized scratches were carefully obtained approximately 0.7±0.2 mm inwidth. Detached cells and debris were washed away with PBS solutionbefore placing the multiwell in the stage incubator.

In both models, the effect of truffle extract, fermented truffle extractand fermented yeast on the rate of wound closure were tested byincubating the scratched monolayer with the following solution: truffleextract 1% w/v, fermented truffle extract 0.5 and 1% w/v and fermentedyeast 1% w/v. The samples were prepared by dissolving the lyophilizedpowders directly in the medium. pH and osmolality (7.2-7.4 and 300 mosm)of the medium containing the treatments were verified to ensurephysiological conditions.

The ‘wound closure’ phenomenon was monitored using a TLVM station, toobserve the migration of cells to repair the wound. In the presence ofdifferent treatments, this allowed simultaneous observation of therepair of different cells and successive performance of qualitative andquantitative analyses of the experiment (D'Agostino et al., 2015, BMCcell biology, 16:19, hereby incorporated by reference).

The fermented truffle extract samples led to complete repair in shortertime compared with truffle extract, fermented yeast and control (Table1).

Example 3 Effect of Fermented Truffle Extract on HSP 70 and HSP 90Induction

20 mg of powder of fermented truffle extract or truffle extract or yeastlysate were resuspended in 1 ml of PBS (physiological conditions) inorder to obtain a final concentration of 20 mg/ml.

2.5 millions of HEK-293t cells were treated with: 1, 2, 5 and 10 mg offermented truffle extract in a final volume of 10 ml (DMEM medium). Thecells were incubated for 18 hrs at 37° C. and then harvested. The cellswere lysated in RIPA buffer (50 mM Tris pH 8, 1% nonidet p40 0.25%Sodium Deoxycholate and 1 mM EDTA) and equal amounts (calculated usingthe Bradford protein assay) of soluble fractions were loaded on SDS-PAGE(10% polyacrylamide). The gel was blotted on PVDF membrane and HSP 70/90were detected using commercial antibodies. Anti-β-actin was used ascontrol. The signals corresponding to HSP 70 and HSP 90 were quantifiedusing Image J software and the results obtained were plotted.

Analyzing the cells treated as described above, it was observed that HSP70 and HSP 90 gradually increased their expression when cells wheretreated with increasing amounts of fermented truffle extract (mg offermented truffle extract/ml of medium). The filters were quantified andthe results obtained were blotted on a graph that clearly indicates apeak of HSP 70/90 expression levels at 1 mg/ml (Table 2)

Data indicate that HEK-293t cells treated with fermented truffle extractshow with a progressive increase, concentration dependent, of HSP 70 andHSP 90 level of expression, this effect is in minor amount present withfermented yeast and absent with non fermented truffle extract.

Example 4 Antioxidant In Vitro Activity of Fermented Truffle ExtractUsing T-BARS (Thiobarbituric Acid Reactive Substances) Assay

Generation of reactive aldehydes were assessed by measuringthiobarbituric acid-reactive substances (TBARS), as described previouslyby Stiuso et al., (Stiuso P., et al., 2014, Oxidative Medicine andCellular Longevity, hereby incorporated by reference). The effect offermented truffle extract on HaCaT cells (2.0×10⁵) was tested in threedifferent experimental setups: (1) cells were pre-treated for 30 minuteswith 50 μM H₂O₂ or with exposure to a UVA radiation (λ_(max) 365 nm),and then incubated with fermented truffle extract (0.32% w/v) for 24 h,to test the protection effect on post-stress process; (2-3) fermentedtruffle extract was applied simultaneously with 50 μM H₂O₂ or withexposure to a UVA radiation 365 nm), to test its antioxidant activity.

The protein concentrations were determined using the Bio-Rad proteinassay reagent (Bio-Rad Laboratories, Milan Italy). Lipid peroxidationwas evaluated using an analytical quantitative methodology. It reliesupon the formation of a colored adduct produced by the stoichiometricreaction of aldehydes (malondialdehydes MDA) with thiobarbituric acid(TBA).

TBARs assay were performed on aliquots of membranes extracted (10 μl)added to 2 ml of TBA-TCA (TCA 15% w/v, TBA 0.3% w/v In HCl 0.12 N)solution at 100° C. for 30 min. The chromogen was quantified byspectrophotometric reading at a wavelength of 532 nm and the amount ofTBARs were expressed as a percentage of lipid peroxidation and thennormalized respect to control. Data reported in Table 3 shows thatfermented truffle extract is effective in all oxidative stressconditions.

Example 5 Production of HA of Different Mw

The strategy used to obtain HA of different Mw is based on anheterogeneous acid hydrolysis of 1800 KDa HA according to Toommeras etal., (Melander C. and Tommeraas K., 2010, Carbohydrate Polymers 82,874-879, hereby incorporated by reference). In particular, HA powder(1800 kDa) hydrolysis in ethanol (EtOH) (93% v/v) was carried out usinga HCl-EtOH vs. HA ratio 10/1 v/w. The slurry was pre-warmed at 65° C. ina thermostatic bath, then a few drops of HCl 37% v/v were added undervigorous stirring, in order to have a final concentration of 0.4M HCl.The hydrolysis was carried out for 60 and 100 min to obtain HA 800 and200 KDa respectively. Each sample was then cooled in an ice-bath andneutralized with an equimolar quantity of NH₃ 25%. Samples were washedwith ethanolic solution (93% v/v), recovered using a Buchner funnelunder vacuum, lyophilized and then stored at −20° C. untilcharacterization was obtained.

HA fragments were characterized by SEC-TDA (Size ExclusionChromatography-Triple Detector Array) equipment by Viscotek (Lab ServiceAnalytica, Italy). A detailed description of the system and itsanalytical conditions are reported by La Gatta et al. (La Gatta et al.,J Biomed Mater Res Part B: Appl Biomater, 104B, 9-18, herebyincorporated by reference).

Samples' molecular weight (Mw, Mn, Mw/Mn) and molecular size(hydrodynamic radius-Rh) are reported in Table 4. The poly dispersityindex ranged from 1.4 to 1.7, which was comparable to the one calculatedfor the HA substrate, confirming an efficient and a simple approach fordegrading HA without further complex purification steps. The decrease ofintrinsic viscosity and hydrodynamic radius were in accordance with thereduction of chain lengths.

In order to confirm if HA, degraded by heterogeneous hydrolysis,maintained its structural integrity, the hydrolysed HA fragments wereanalyzed by ¹H-NMR spectroscopy. As expected, the ¹H-NMR spectra showedthe presence of peaks corresponding to acetamide protons at 1.9 ppm, 2′,3′, 4′, 5′, and 6′-protons of HA disaccharide unit at 3.2-4.0 ppm, aswell as anomeric l′-protons at 4.4 ppm. No indication of suspectedby-products such as de-N-acetylation or ethanolysis at the reducing-endwere observed.

Endotoxin amount determination—For endotoxin content determination, HApowders were dissolved in pyrogen free water. The amount of pyrogens(bacterial endotoxins) in the solution were measured by using LimulusAmebocyte Lysate (LAL) testing (chromogenic kinetic method) according toEuropean Pharmacopoeia 01/2005:20614. Specifically, ENDOSAFE®-PTScartridge US License N.1197 by Charles River Endosafe were used. Alloperations were performed under conditions avoiding endotoxincontamination. Results were reported as endotoxin units (EU/mg) of HApowder. The low endotoxin content, crucial in pharma grade requirements,is of key importance to better highlight the HA fragment functionitself. The endotoxins amount for all hyaluronan powders produced,resulted in less than 0.05 EU/mg. This data proved that LPS and/orendotoxin are below a guard level and therefore cellular phenomenonshould be driven by HAs rather than impurities.

Example 6 HAs: In Vitro Keratinocytes and Fibroblasts Scratch Assay,Using TLVM

HaCaT and HDF cell line and their growth conditions are described hereinabove in Example 2. In both models, the effect of HA gels on the rate ofwound closure was tested by incubating the scratched monolayer with thefollowing solutions: HA1800 KDa, HA800 KDa, HA200 KDa, HA1800 KDa+HA800KDa (50% w/w each), and HA1800 KDa+HA800 KDa+HA200 KDa (33.3% w/w each)at final concentration of 1% w/w in the incubation medium. The sampleswere prepared by dissolving the lyophilized powder directly in themedium. pH and osmolarity (7.2-7.4 and 300 mosm) of the mediumcontaining the treatments were verified to ensure physiologicalconditions.

The ‘wound closure’ phenomenon was monitored using a TLVM station toobserve the migration of cells to repair the wound. In the presence ofdifferent treatments, this allowed simultaneous observation of therepair of different wells and successive performance of qualitative andquantitative analyses of the experiment (D'Agostino et al., 2015 BMCcell biology, 16:19).

The highest Mw HA samples led to complete repair in shorter time;however, all the HA fragments tested enhanced the scratch repair ratecompared to the control (Table 5).

Mixtures formed by equivalent amounts in weight of HA1800+HA800 KDa andHA1800+HA800+HA200 KDa are characterized by a significant reduction inthe repair time with respect to HA separately (Table 5).

Example 7 HAs: Gene Expression Analysis in Stressed Cells

For gene expression analyses in stressful conditions, humankeratinocytes and fibroblasts were grown in different cell cultures.3.75×10⁴ cells/cm² were seeded in a standard 24-well culture plate. Toreproduce skin inflammation in vitro, the mechanical injury induced tothe cultures was very extensive. With a sterile tip, parallel scratcheswere inflicted upon the monolayers, estimating damage to be at least 40%of the cells.

After addition of HAs and incubation for 16 h the cells were directlylysed with TRIzol® (Invitrogen, Milan, Italy). Total RNA was extractedfrom HA (Mw=1800, 800 and 200 KDa) treated keratinocytes or fibroblasts.Following precipitation with isopropyl alcohol and washing with 75%ethanol, the RNA pellets were resuspended in nuclease-free water. Theconcentration of the extracted RNA was determined through a Nanodropspectrophotometer (Celbio, Milan, Italy) and 1 μg of DNase-digestedtotal RNA was retro-transcripted in the cDNA using Reverse TranscriptionSystem Kit (Promega, Milan).

Quantitative real time PCR was obtained by iQ™ SYBR® Green Supermix(Bio-Rad Laboratories Srl) in order to analyze the gene expression ofsome HA key receptors such as CD44 and RHAMM, TLR4 and alertinflammation biomarkers such as TGF-β, TNFα, IL-6. The primer sequences(Table 6) were designed by Beacon Designer™ software. The final meltingcurve was performed from 55-95° C.

Samples were run in triplicate, and the expression of specific mRNArelative to the control was determined after normalization with respectto HPRT housekeeping gene (internal control). The fold-change of mRNAexpression of the genes under evaluation was calculated by using the2-ΔΔCt comparative threshold method (ΔΔCt=difference of ΔCt betweentreated cells and non-treated cells used as controls). The results wereexpressed as normalized fold expression, calculated by the ratio ofcrossing points of amplification curves of several genes and internalstandard, by using the Bio-Rad iQ™5 software (Bio-Rad Laboratories Srl).Gene expression data analyses for the main HA receptors are reported inTable 7. CD44 was to be over expressed for all HA evaluated. All HAsamples increased RHAMM expression, however results were significantlyhigher for 200 KDa.

Inflammation biomarkers (TGFβ-1, TNF-α and IL-6) involved in epithelialcell migration were evaluated by quantitative RT-PCR. Specifically,TGFβ-1 was up-regulated for all HA fragments investigated. HA rangingfrom 800 to 200 KDa, showed a significant increase in TGFβ-1 withrespect to HA1800 KDa.

In this case the increase prompted a “positive” activation toward therepair. Cell repair activation mechanism, implicate also IL-6 that isregulated by HA/receptor interaction. Results showed that both TNF-α andIL-6 present similar trend during re-epithelisation process. Inparticular the expression levels increased with the HA molecular sizedecreasing.

Example 8 HAs: Antioxidant In Vitro Activity Using T-BARS(Thiobarbituric Acid Reactive Substances) Assay

The experiment was conducted as reported in the Example 4. The effect ofHAs 1800+800+200 KDa mixture (33.3% w/w each) at final concentration of0.5% w/v in the incubation medium, on HaCaT cells (2.0×10⁵) was testedin three different experimental setups: (1) cells were pre-treated for30 min with 50 μM H₂O₂ or with exposure to a UVA radiation (λ_(max) 365nm) and then incubated with HAs mixture (0.5% w/v) for 24 h, to test theprotection effect on post-stress process; (2-3) HAs mixture were appliedsimultaneously with 50 μM H₂O₂ or with exposure to UVA radiation(λ_(max) 365 nm) to test antioxidant activity.

Data reported in Table 8 show that HAs 1800+800+200 KDa mixture (33.3%w/w each) is effective in the oxidative stress conditions.

Example 9 Preparation of Olive Leaf Extract in Thermal Water andCharacterization of Actives

10 Kg of fresh Olive leaves, collected from centuries-old olive trees ofPuglia, Italy, were washed first with water a plurality of times, thensuspended in 40 L of thermal water from the Thurio spring at theSpezzano Thermal Baths, Italy. Then they were homogenized for 1 h withan ultra Turrax blender. At the end of extraction process (24 h, 4° C.,pH 5.5-6.5) the slurry was clarified by continuous centrifugation onAlfa Lavall centrifuge and the clear pale green supernatant was directlyused in the cosmetic formulate.

To characterize the extract the solution was lyophilised. Quantitativechemical characterization of actives present in the extract indicates asolid residue of 50 g/L of extract containing per g of powder 50 mg ofoleuropein, 6 mg of minor olive polyphenol and 1 mg of flavonoids.

Data reported in Table 10 show that Olive leaf extract in thermal wateris effective in but the oxidative stress conditions.

Example 12 Production of Fermented Grapes of Falernum

50 Kg of fresh grapes collected from Falciano del Massico, (Italy)vineyards (the same used by ancient Romans to produce the most expensiveand famous Faustian Falernian wine) were washed twofold with water, andafter premixing were homogenized for 1 h with an ultra Turrax blender.At the end of fermentation process (48 h, 10° C., pH 5) the slurry wasclarified by under pressure filtration and pasteurised.

25 L of a stable solution of a brilliant ruby was obtained, rich inpolyphenols with antioxidant activity and a complex mixture ofcarbohydrate and peptide compounds, which confer a strongbiorevitalizing action.

The ‘wound closure’ phenomenon was monitored using TLVM station, toobserve the migration of cells to repair the wound (D'Agostino et al.,2015 BMC cell biology, 16:19, hereby incorporated by reference). Results(Table 11) indicate a reduction of the wound closure time in presence offermented grapes of Falernum to about half of the control for both thecellular systems used.

Example 14 Fermented Grapes of Falernum: Antioxidant In Vitro ActivityUsing T-BARS (Thiobarbituric Acid Reactive Substances) Assay

The experiment was conducted as reported in Example 4. The effect offermented grapes of Falernum at final concentration of 10% v/v in theincubation medium, on HaCaT cells (2.0×10⁵) was tested in threedifferent experimental setups: 1) cells were pre-treated for 30 min with50 μM H₂O₂ or with exposure to a UVA radiation (λ_(max) 365 nm) and thenincubated with fermented grapes of Falernum (10% v/v) for 24 h, to testthe protection effect post-stress process; (2-3) fermented grapes ofFalernum were applied simultaneously with 50 μM H₂O₂ or with exposure toUVA radiation (λ_(max) 365 nm) to test antioxidant activity. Datareported in Table 12 show that fermented grapes of Falernum is effectivein all the oxidative stress conditions.

Example 15 Cytomimetic Formula Preparation

1 L of fermented grapes of Falernum, prepared as reported in Example 10,were mixed with 0.5 L of Olive leaf extract in thermal water, preparedas reported in Example 8. This solution was diluted with 3 L ofdeionized water and under agitation 0.3% EDTA, 0.4% sodium benzoate,12.5 g of 1800 KDa HA, 12.5 g of 800 KDa HA and 12.5 g of 200 KDa and 5g of fermented truffle extract prepared as reported in Example 1 wereadded.

The pH was corrected at 6.5 with 3% NaOH solution and the solution wasdiluted with deionized water up to 5 L. A clear ruby solution wasobtained.

The resulting composition of the cytomimetic formula is: fermentedtruffle extract powder 0.1% (w/v); fermented grapes of Falernum 20% v/v;Olive leaf extract in thermal water 10% v/v; and HA 1880, 800, 200 KDaeach 0.25% w/v.

Example 16 Synergistic Action of Actives of the Cytomimetic Formulas: InVitro Scratch Wound-Healing Assay Using TLVM

HaCaT and HDF cell line and their growth conditions are describedhereinabove in Example 2. In both models, the effect of the cytomimeticformula on the rate of wound closure was tested by incubating thescratched monolayer with a final concentration of 1% and 2% v/v in thecell growth medium.

The ‘wound closure’ phenomenon was monitored using a TLVM station toobserve the migration of cells to repair the wound (D'Agostino et al.,2015 BMC cell biology, 16:19). Results (Table 9) indicate a reduction ofthe wound closure time in presence of the cytomimetic formula to about ¼of the control for both the cellular systems used. The data in Table 13demonstrate a potent synergistic effect of the actives present in thecytomimetic formula, which in this experiment are present up to threeorders of magnitude in respect to that reported in Examples 2, 6, 10 and13 for the single actives.

Example 17 Synergistic Action of Actives of the Cytomimetic Formula:Antioxidant In Vitro Activity of the Cytomimetic Formula Using T-BARS(Thiobarbituric Acid Reactive Substances) Assay

Generation of reactive aldehydes was assessed by measuringthiobarbituric acid-reactive substances (TBARS), as described previouslyby Stiuso et al., (Stiuso P., et al., 2014, Oxidative Medicine andCellular Longevity). The effect of the cytomimetic formula on HaCaTcells (2.0×10⁵) were tested in three different experimental setups: 1)cells were pre-treated for 30 min with 50 μM H₂O₂ or with exposure to aUVA radiation (λ_(max) 365 nm) and then incubated with cytomimeticformula (0.1 or 0.5% v/v) for 24 h, to test the protection effectpost-stress process; (2-3) cytomimetic formula (0.32% w/w) was appliedsimultaneously with 50 μM H₂O₂ or with exposure to UVA radiation(λ_(max) 365 nm) to test antioxidant activity.

The protein concentrations were determined using the Bio-Rad proteinassay reagent (Bio-Rad Laboratories, Milan Italy). Lipid peroxidationwas evaluated using an analytical quantitative methodology. It reliesupon the formation of a colored adduct produced by the stoichiometricreaction of aldehydes (malondialdehydes MDA) with thiobarbituric acid(TBA).

TBARs assay were performed on aliquots of membranes extracted (10 μl)and added to 2 ml of TBA-TCA (TCA 15% w/v, TBA 0.3% w/v in. HCl 0.12 N)solution at 100° C. for 30 min. The chromogen was quantified byspectrophotometric reading at a wavelength of 532 nm and the amount ofTBARs were expressed as a percentage of lipid peroxidation and thennormalized with respect to control.

Data reported in Table 14 show whether oxidative stress occurred beforeor with the addition of the cytomimetic formula was effective.

Example 18 Synergistic Action of Cytomimetic Formulate: Effect on HSP 70and HSP 90 Induction

2.5 millions of HEK-293t cells were treated with a cytomimeticformulation at 0.1 and 0.5% v/v in a final volume of 10 ml (DMEMmedium). The cells were incubated for 18 h at 37° C. and then harvested.The cells were lysated in RIPA buffer (50 mM Tris pH 8, 1% nonidet p400.25% Sodium Deoxycholate and 1 mM EDTA) and equal amounts (calculatedusing the Bradford protein assay) of soluble fractions were loaded onSDS-PAGE (10% polyacrylamide). The gel was blotted on PVDF membrane andHSP 70/90 were detected using commercial antibodies. Anti-β-actin wasused as control. The signals corresponding to HSP 70 and HSP 90 werequantified using Image J software and the results obtained were plotted.

Analyzing the cells treated as described above, it was observed that HSP70 and HSP 90 gradually increased their expression when cells wheretreated with increasing amounts of the cytomimetic formulation.

Data from Table 15 indicate the potent synergistic effect of activespresent in the cytomimetic formulation, that in this experiment arepresent at an average two orders of magnitude with respect than thatreported in Example 3 for the fermented truffle extract alone.

Example 19 Cytomimetic Formulate: Gene Expression Analysis in StressedCells

The gene expression analyses of the cytomimetic formulation in stressfulconditions was performed at 0.1 and 0.5% v/v as described hereinabove inExample 7. Gene expression data analyses are reported in Table 16. CD44,RHAMM, TGFβ-1, TNF-α and IL-6 are all up-regulated increasingCytomimetic formulate concentration, only TLR-4 activity, correlated toinflammatory process, is significantly down-regulated.

Example 22 Clinical Testing Methodology

The testing application of the base composition and base compositionusing a cytomimetic formulation is made by subjects morning and night,through a gentle massage, so as to have full-absorption of the product.The measurements will be done in the right and left zygomatic arch (1cm. extension of the external angle), on the cleansed skin, having notused make-up in the previous 24 hours. This is done afteracclimatization of the subjects for at least 10 minutes in constanttemperature/humidity conditions. Each of the two products will beevaluated against baseline initial measurements.

The efficacy will be appreciated through instrumental, non-invasivenessmethods: moisture of corneum layer (Corneometry), sebumetry, elasticityand firmness, SELS (Surface Evaluation of Living Skin) parameters:roughness, smoothness, the scaliness degree, wrinkles). Successivemeasurements will be done, as follows: for moisture (triplicate in eachpoint: left/right), for sebumetry, elasticity, firmness and profilometryan unique measurement right/left. as follows: for the hydration(Comeometer MPA 580, Courage+Khazaka electronic GmbH), sebumetry(Sebumeter SM 815, Courage Khazaka electronic GmbH), elasticity(cutometer MPA 580, Courage+Khazaka electronic GmbH), profilometry(Visioscan VC80, Courage+Khazaka electronic GmbH).

Skin Hydration is determined instrumentally, through Corneometry.Measurement principle: measuring the capacitance. Water increases thecapacitance of the capacitor as compared with a vacuum capacitor(C=εS/d). The water dielectric constant c is 81, as compared with othersubstances <7 and the vacuum dielectric constant is 1. The changes incapacitance due to variations in the dielectric constant give the levelof hydration. The corneometer measures the water content in the surfaceepidermal layer up to a depth of 0.1 mm.

The sebumetry is determined instrumentally, with the help of asebumeter. The measurement is based on the absorbance of a plastic filmimpregnated with sebum is determined through photometry, the filmbecoming transparent in the presence of the lipids. The sebum valuesthat can me measured are between 50-300 μg/cm². Values exceeding 300μg/cm² indicate excess sebum supersaturation and may be subject tomeasurement errors, while values below 50 μg/cm² show that there is nolinearity between the values and the sebum content.

Measurements for skin elasticity are made with a Cutometer. Themeasurement principle is based on suction and elongation. The devicegenerates a negative pressure between 20 and 500 mbar which “sucks up” adefined skin area it is applied to. In order to measure the mechanicalcharacteristics of the epidermis 2 mm diameter probes are necessarywhile for the dermis and hypodermis—10 mm diameter probes. Whenmeasuring the elasticity parameters it is important to set the suctionpressure according to the characteristics of the skin (e.g.: the skinaround the eyes is thinner—the suction pressure is lower). Themeasurements will be done in Module 1, with a 2 mm probe, negativeconstant pressure 350 mbars, 2 seconds time of the suction andrelaxation. The number of repetitions will be 10, in order to evaluatethe skin firmness and the tiredness resistance.

The testing method is called SELS (Surface Evaluation of the LivingSkin) and it is based on the graphic illustration of the skin surface inspecial lighting conditions. This image is processed electronicallytaking into account four clinical parameters which correspond to thephysiological conditions of the skin surface both from the quantitativeand from the qualitative point of view and which derive from theroughness conventional parameters.
